Article sorting system and method

Abstract

The invention discloses an article sorting system and method. The system involves a server and a plurality of carrying robots; the plurality of carrying robots operate in a storage area, a plurality of sets of grids are arranged in the storage area, and each set of grids at least comprises a first type of grids and a second type of grids; the server is configured to determine that the grids with the number of the articles, loaded by a loading container, reaching a preset threshold value are target grids, determine first obstacle grids hindering moving of the target grids when the target gridsare the second type of grids, distribute one carrying robot to each of the first obstacle grids and the target grids from the plurality of carrying robots, and send carrying instructions to the carrying robots; the first carrying robots are configured to respond to the carrying instructions to travel to the first obstacle grid positions and carry the loading containers away the first obstacle gridpositions; and the second carrying robots are configured to respond to the carrying instructions to travel to the target grid positions and carry the loading containers at the target grid positions to a packaging table. According to the system and method, the article sorting efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of intelligent logistics, and in particular to an item sorting system and method. Background technique [0002] With the development of e-commerce, severe requirements are put forward for the logistics industry. For example, how to efficiently and accurately sort logistics items, etc. [0003] At present, the following two methods are often used for sorting items: Method 1, as shown in Figure 1(a), adopts a steel platform sorting structure, by controlling the robot to receive the items provided by the supply table on the steel platform, and combining the steel The auxiliary equipment set on the platform delivers the items to the grids on the steel platform; the second method, as shown in Figure 1(b), adopts a landing zigzag sorting structure, and controls the robot to land on the grid with grids. The zig-zag sorting field receives the items provided by the supply platform, so as t...

Problems solved by technology

[0004] However, the above two sorting methods have the following problems. For the first method: although the purpose of item sorting can be achieved, it takes a lot of cost to build a steel platform, and the steel platform is not easy to expand, so that the robot performs item sorting on the steel platform During the task, the flexibility is poor, and it is easy to be limited by the number of auxiliary equipment, resulting in a decrease in the efficiency of item sorting; for the second method: when the number of robots is large and the density is high, the robot is prone to congestion in the sawtooth area when performing item sorting tasks , leading to a decrease in item sorting efficiency
